Consumtion and engine choise?

(i know it´s not rib related) But the consumtion is probably interesting for everyone who click this thread.

We have plans for one or two workboats for transportation of materials and smaller machines. In the archipelago of stockholm. 99% inshore.

First boat is 24-26f (mono or multihull)
Two outboard engines
115
150
175



Second boat is 34-36f (mono or multihull)
Two outboard engines
150
175
or up to 250

Two diesel engines
D3 200
D6 350

I understand the consumtion depends on weight of boat but if we say a empty boat and a full loaden boat.

How much fuel each hour for each engine/boatchoise?
How much fuel each NM?

At least specify engine brands, 2 or 4 strokes to start with something.

2 strokes carbed engines will consume about 12 % of it's rated HP in gallons per hour work at full throttle, 4 strokes 30% less compared to 2 strokes. Etecs, TLDI are more gas efficient than carbed 4 strokes engines. Will also depend on the type of hull, water conditions, wind, boat weight, propeller etc. Better ask a Suzuki distributor, as this info is in the tech service manuals.

Happy Boating

Have a look at Boston Whaler's website - loads of perfromance data but all Mercury I think.
